Abstract
Disclosed is a multi-carrier method for digital data transfer, especially for electrical power distribution networks. According to the invention, N amounts of symbols are assigned to combinations of Id(N) data bits on the basis of the data flow to be transmitted in order to achieve quick and interference-free transfer. Each symbol consists of N signal forms with different frequencies. On the receiver side, a series of 2N digital signal-adapted parallel-working filters are used for simultaneous incoherent optimal reception of all N signal forms used to represent a symbol. A digital numerical value corresponding to the signal form energy is formed as correlation value for each of the N signal forms. An evaluation and scaling of N correlation values is carried out by comparison with a freely chosen threshold. The correlation values forming a symbol are added to obtain the corresponding symbolic value. The corresponding functional units can be advantageously integrated into an ASCI to implement the inventive method.
